What is rotary shaker?
Definition and application
is laboratory equipment for mixing and growing chemicals, solvents, and other laboratory samples. They are widely used in basic chemicals, pathological work analysis, and other scientific fields. In addition, rotary shakers can also be used to shake solutions in the Erlenmeyer flask.
Rotary shaker working principle
The working principle of the rotary shaker is mainly an LC circuit consisting of a capacitor and an inductor, which produces free oscillations through the interconversion of the electric and magnetic field energy. As the positive feedback becomes stronger and stronger, it leads to a transient steady state. During the transient state, another transistor is gradually charged by the capacitor and then turns on or off, and the state is flipped and another transient state is reached. This way the principle of oscillation is formed over and over again.
Rotary shaker function
There are many functions of the rotary shaker machine, but it can be summed up in four main functions:
1. To make the solution even out
In general, whatever the type of rotary shaker, the main function is to oscillate and mix samples at a certain temperature and speed, so that the solution is evenly distributed.
In addition, in biochemical research or experiments, rotary shakers are used for the culture of microorganisms, such as bacteria in liquid media.
2. Homogenize a solution of high viscosity
Because the swing angle and vibration speed of the rotary shaker can be changed, even if the viscosity or density of the sample is quite high, the rotary shaker can also homogenize the sample.
3. Homogenize nutrients
One type of rotary shaker is the rotary shaker incubator, which is actually a combination of the shaker and the incubator. The shaker produces vibrations, and the incubator maintains certain conditions necessary for the microbial culture process, so the function of the rotary shaker is to homogenize nutrients.
4. Samples can be homogenized at low temperatures
Some sample solutions need to be processed at low temperatures, and rotary shakers can be a good solution to this problem, because in rotary shakers, there is a type of rotary shaker because of its low speed, so the vibration frequency of the shaker is very low, the temperature is also relatively low. Therefore, the rotary shaker is very suitable for the culture of microorganisms.

Rotary shaker safe operation
When using the rotary shaker, in order to avoid unnecessary equipment failures and to ensure the safe operation of the equipment, please follow the following requirements:
Place the rotary shaker on a level table or work table that can support the weight of the shaker and all related components.

How to use rotary shaker?
1. When the rotary shaker rotates at high speed, in order to avoid large vibration of the instrument, the culture reagent bottles should be placed symmetrically on the shaker, and the culture liquid of each bottle should be roughly equal.
2. Please firmly fix the sample on the shaker, make sure that the sample will not swing violently when the shaker is working before leaving.
3. In the sampling process, if any sample is found missing that is including the plug drop, the total power supply should be turned off, and the debris should be removed with tweezers as far as possible. If necessary, part of the parts should be removed for cleaning.
4. It is forbidden to put the pipe frame made of plastic foam into the shaker, so as not to inhale the foam particles into the rotating shaft of the fan, resulting in overheating and burning of the fan!
5. When taking out the sample, turn off the power or set the speed to zero.
How to maintain rotary shaker?
1. The surface of the rotary shaker should be cleaned frequently to keep it clean, and the side of the instrument control panel should be avoided to avoid water droplets entering the instrument and damaging the instrument.
2. When the instrument is often used, an appropriate amount of grease should be added every few months, and the fuse box, control components and fastening screws of the instrument should be checked regularly.
3. after long-term use, equipment failure, should be repaired by professional maintenance personnel, can not be easily disassembled.
4. When the shaker is not used for a long time, especially in the rainy season or wet season, it should be powered on regularly (every 1 month) for 5-8h to remove the moisture absorbed by the electrical components of the equipment.
